SPOKE-SOCKET.

SPECIFICATION forming part of Letters Patent No. 417,711, dated December 24, 1889'. Application filed September 19, 1889. Serial No. 324,384. (No model.)

To all whom it may concern.-

Be it known that I, JAMES R. MOALISTER, a citizen of the United States, residingat Rossie, in the county of St. Lawrence and State of New York, have invented certain new and useful Improvements in Spoke-Sockets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in spoke-sockets, which will be hereinafter fully described, and particularly pointed out in the claims.

The common practice of uniting a spoke to to a felly of I a vehicle is to form a large aperture or socket in the telly to receive a tenon on the outer end of the spoke; but this is objectionable, because it tends to weaken the felly.

The primary object of my invention is to overcome this objection by providin a socket which will receive the spoke, and thus preserve the telly entire and materially strength en the joint at its weakest partnamely, where the spoke is united to the felly.

Heretofore a'spoke-so'cket and felly have been cast in a single piece of metal; but I propose to make the telly-clasp and the spoke socket in separate pieces of metal as, for instance, shcet steel and to unite the two parts permanently together in a novel manner. By making the device in two parts of thin sheet steel and uniting them together the weight of the sockets in an entire wheel is very materially reduced without sacrificing the necessary strength and stability, which is very desirable, the device can be more conveniently manufactured, it is less exposed to view and abrasion, and is more durable than cast-metal sockets and 'clasps.

To enable others to understand my invention, I will now proceed to a detailed description thereof in connection with the accompanying drawings, in which- Figure 1 is a view of my improved felly applied to a vehicle-wheel. Fig. 2 is a vertical sectional view through the spoke socket and clasp. Figs. 3 and at are detached views of the socket and clasp, respectively. Fig. 5 is a vertical section of a modified form of the socket.

Like numerals of reference denote corresponding parts in all the figures of the drawings, referring to which 1 designates my improved sp0kes0cket, which consists of a socket 2 and a clasp 3, which are made of separate pieces of metal and permanently united together in a novel manner, as will be presently described.

In the preferred embodiment of my invention I stamp a blank for the felly-clasp 2 out of a single piece of sheet metal, and then bend the blank into the concavo-conveX shape shown in Fig. 4. The clasp is provided at its edges with coincident apertures at 4, through which bolts, rivets, or other suitable contrivances can be passed to secure the clasp to a felly, and in its crown or apex the clasp has two or more transverse apertures 5, for a purpose which will presently appear.

The socket 2 is made by stamping a blank from a piece of sheet metal, bending it into the desired cylindrical shape, and uniting the meeting edges of the blank together in any suitable manner. At one end the socket is provided with studs or tenons 6, preferably two in number and located at diametricallyopposite points, and these tenons are made integral with the socket by being stamped out of the sheet of metal at the same time with the blank of which the socket is made. The lower end of the socket is recessed or shaped to fit snugly over the concayo-convex felly clasp, and the clasp and socket are permanently united together by heading the tenons or studs 6 down on the inner side of the clasp, said tenons passing through the apertures 5 in the crown of the clasp.

The device is used byfitting the clasp snugly over the telly and securing it firmly on the latter by means of rivets or bolts 7, which pass transversely through the folly and the coincident apertures 4' I in the clasp, and the tenon on the spoke is fitted in the socket and securely held in place by the same on the felly. The clasp and socket thus serve' to therein.

and socket out of thin sheet-steel, which possesses the necessary strength and is light, so that the weight of a series of clasps and sockets, constructed as specified and applied to a Wheel, is less than a correspondingnumber of cast-metal sockets, which is very desirable.

By making the clasp and socket in separatepieces and uniting them together the device can be very conveniently manufactured, is less exposed to view and abrasion, and is more durable than cast-metal sockets. I also contemplate casting the socket et in a single piece of metal and uniting it to the sheet-metal clasp. \Vhen the socket is cast, the wall thereof is tapered from its upper toward its lower end to facilitate withdrawing the same from sand or mold, and the tenons are made integral with the socket, as shown in Fig. 5, and the two parts are united together by fitting the socket on the clasp, so that the tenons of the socket enter the apertures in the clasp, and heading the tenonsdown on the inner face of the clasp, as is obvious.

As a further modification of my invention, the clasp may be cast in a single piece of metal with the apertures in its crown and the socket cast in an other piece. hen the socket is cast separate from the clasp, it can be made thinner and lighter than it is possible to make the device when made of a single piece of metal. The hole in the socket is tapering to permit the pattern to be easily drawn from the sand and to adapt the socket to fit the tenon of the spoke tightly and snugly.

The cast-metal socket may have its outside taper to correspond with the inside taper, the thickness of the wall of the socket being uniform throughout; but in cases where the sockets are cast connected with the clasp the sockets must be of reverse taper as to inside and outside taper in order to draw from the sand.

Slight changes'in the form and proportion of parts can be made without departing from the spirit or sacrificing the advantages of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As an article of manufacture, a combined spoke-socket and telly-clasp consisting, essentially, of a clasp made of asingle piece of metal and having the transverse apertures, and a socket made of another piece of metal and provided with the tenons which are fitted in the apertures of the clasp and headed down thereon to permanently unit-e the clasp and socket together, substantially as described.

2; As an article of manufacture, a combined spoke-socket and telly-clasp consisting of a clasp shaped to snugly fit a telly, and a socket which is made separate from the clasp, the two parts beingpermanently united together, substantially as described.

3. A combined spoke-socket and clasp consisting of a curved clasp and a socket made separate from the clasp and curved or recessed at its lower end to lit snugly on the back of the clasp, the clasp and socket being riveted together, substantially as described.

4. In a combined spoke-socket and clasp, a clasp made of a single piece of sheet metal bent into the desired curved shape and having the central apertures, and a socket also made of a single piece of sheet metal which is bent into cylindrical form and shaped at its lower end to fit snugly on the back of the clasp, said socket having the integral tenons at its lower end which are fitted in the central apertures in the clasp and are headed down onthe inner face thereof, substantially as described.

In testimony whereof I affiX my signature in presence of two witnesses.
